 Storm Water Needs Assessment and website 

The City's has hired an engineering firm, HR Green, to perform a citywide storm water needs assessment.  In order to collect data from the residents of the community, they have created a user-friendly website.   Residents are encouraged to input their storm water concerns directly into the website.  This information, along with input collected at public meetings,  will be compiled into a map and report of the storm water problem areas.
